121247-90-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121247-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,4 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121247-90:
(8*1)+(7*2)+(6*1)+(5*2)+(4*4)+(3*7)+(2*9)+(1*0)=93
93 % 10 = 3
So 121247-90-3 is a valid CAS Registry Number.
